In Vitro Evidence for Oral Soft Tissue Regenerative Effects of a Polynucleotide–Hyaluronan Formulation

open access: yesClinical and Experimental Dental Research
Objectives We aimed to investigate the effects of a polynucleotide–hyaluronan (PN–HA) formulation on human palatal fibroblasts (HPFs) and oral epithelial cells (OKF6/TERT‐2) to assess its potential application in oral soft tissue reconstructive ...

Polynucleotide HPTTM-Based Hydrogels Exhibit Scavenging Activity Against Reactive Oxygen Species

open access: yesAntioxidants
This study investigates the scavenger activity of Polynucleotide High Purification Technology (PN HPTTM), alone or in combination with hyaluronic acid (PN HPTTM + HA) against oxidative stress induced by hydrogen peroxide (H2O2). Since oxidative stress is

Origin of the Genetic Code Is Found at the Transition between a Thioester World of Peptides and the Phosphoester World of Polynucleotides

open access: yesLife, 2019
The early metabolism arising in a Thioester world gave rise to amino acids and their simple peptides. The catalytic activity of these early simple peptides became instrumental in the transition from Thioester World to a Phosphate World.

Human APOBEC3G suppresses homologous recombination and LIG4‐independent end joining in DNA double‐strand break repair

open access: yesThe FEBS Journal, EarlyView.
Chromosomal DNA double‐strand breaks (DSBs) are repaired by homologous recombination and nonhomologous end joining (NHEJ). Recent work has additionally established theta‐mediated end‐joining (TMEJ) as a mechanism for DSB joining. Cells lacking NHEJ and TMEJ can repair DSBs in a homology‐dependent manner.

Patent landscape analysis of inventions based on plant genetic resources for food and agriculture and related digital sequence information

open access: yesThe Journal of World Intellectual Property, EarlyView.
Abstract This article provides an overview of the patent landscape in relation to PGRFA‐based inventions involving naturally occurring (“native”) traits and related Digital Sequence Information/Genetic Sequence Data (DSI/GSD). In particular, it focuses on the potential of patent claims to limit others' uses of PGRFA and related DSI/GSD on which the ...
